The world's cleanest food: Antarctic krill is eaten at least 200 million tons a year
Antarctic krill is the largest and most successful single species of multi-cellular organisms on earth, and is the basis for the survival of large organisms in the entire Antarctic ecosystem. It is rich in protein, amino acids, and calcium, phosphorus, potassium, and sodium, which are necessary for the human body, and is also known as the "king of nutrition" because it contains natural antioxidants, as well as astaxanthin. It is estimated that at least 200 million tons are eaten each year, as humans and whales compete to eat it.
